Roof glass shattered.

[maccheeseboy]

Ok so imply put glass was shattered when I bought. Have replacement that looks too big. But serial number matches. I have the old glass off with 4 bolts. very easy. Buuut how do I put new one on? 2002 liberty 3.7. Sunroof? moon roof? i dont know. replacement came with 4 bolt holes, but they do not line up with oem on frame. Do i have to replace the whole track? Or do i have to install by putting window inside jeep and lift up? or drop track, install glass, then reinstall track? Any help is appreciated.
